Based on new data from ESA's Gaia satellite, astronomers have provided more insights into properties of the nearby open cluster NGC 2682, revealing that its size is at least two times greater than previously believed. The ...
An international team of astronomers has detected a new ultra metal-poor star with the lowest ever measured abundance of iron. Designated SMSS J160540.18−144323.1, the newly found object is the most iron-deficient star ...
The chrome plating on the Terracotta Army bronze weapons—once thought to be the earliest form of anti-rust technology—derives from a decorative varnish rather than a preservation technique, finds a new study co-led by ...

Analyzing data from spectroscopic instruments, astronomers have reported fundamental properties of Barnard 29, an ultraviolet-bright star in globular cluster Messier 13. Results of the analysis, presented in a paper published ...
A group of scientists led by Avrajit Bandyopadhyay of the Indian Institute of Astrophysics, Bangalore, has conducted chemical analysis of two bright, extremely metal-poor stars. The results of the analysis, presented May ...
Italian researchers have investigated the chemical composition of NGC 5824, a massive globular cluster in the Milky Way galaxy. Their analysis, based on observational data provided by the Very Large Telescope array, offers ...
Over 3500 extra-solar planets have been confirmed to date. Most of them were discovered using the transit method, and astronomers can combine the transit light curves with velocity wobble observations to determine the planet's ...
